如何根据中文名称获取拼音首字母？

打个比方吧，中国这个词语，我要用js获取词语中第一个词的首字母拼音也就是“Z”，
这个该怎么做？有人做过类似的吗？

    帮你找了一段。受篇幅限制，$PinYin.ds = {};放到2楼
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

            var $PinYin = new Object();
            var $ = function(o) { if (o) { return document.getElementById(o); } }
            $PinYin.ds = {};
            $PinYin.change = function(ch) { for (var n in $PinYin.ds) { if ($PinYin.ds[n].indexOf(ch) != -1) return n; } return ch; }
            $PinYin.search = function(val) {
                var py = "";
                for (var i = 0; i < val.length; i++) {
                    var ch = val.charAt(i);
                    if (/^[\u4E00-\u9FA5]$/.test(ch)) ch = $PinYin.change(ch);
                    py += ch
                }
                return py;
            }
            $PinYin.searchCap = function(val) {
                var py = "";
                for (var i = 0; i < val.length; i++) {
                    var ch = val.charAt(i);
                    if (/^[\u4E00-\u9FA5]$/.test(ch)) ch = $PinYin.change(ch);
                    py += ch.charAt(0);
                }
                //return py;
                $('en').value = py;
            } 
        </script></head>
    <body>
    <input type="text" id="ch"  onblur="$PinYin.searchCap(this.value)"/>
    <input type="text" id="en" />

    还是太长了。看这里吧

  3.   

    说简单点，就是需要做字库,给个简单的例子
    <script>
    var hanzi = "中美俄英法";
    var zimu = "zmeyf";
    function getZiMu(str){
    return zimu.charAt(hanzi.indexOf(str));
    }
    alert(getZiMu("美"));
    </script>
      

  4.   

    这个问题转化为取一个汉字的拼音.你可以通过取字串首字符来取首个汉字,得到其拼音后,再取其字符就是首个声母.
    方式很多,从最笨到较好一些的顺序开始列一些:1.字库查找法:把所有字和其对应的拼音放入一或两个数组中,依次查找.2.关键字库对比法:汉字的排列基本是按照拼音的顺序排的,因此,可以分成多个拼音区间(如BA,BAI,BAN这样的段)的代表汉字摘出来,和其对应的拼音,放入一或两个数组中,用你要处理的汉字去进行比较,判断在哪个区间里.3.和上面类似的,有用汉字内码代替汉字字符来存储的.4.针对楼主的需求,你只需要声母而已,因此,需要摘取的关键字库是很少的.用第2种方法就可以了.
